The incidence of colorectal cancer of Korea is much lower than that of Western countries, but has shown a tendency to a slight increase recently Barium enema is the most valuable, noninvasive and inexpensive method available to evaluate the size, shape and site of colorectal cancer. The authors reviewed and radiologically classified barium enema studies of 232 cases of colorectal cancer from Aug. 1967 to July 1982 at Presbyterian Medical Center, Jeon-ju , Confirmed clinically, operatively and pat hologically. The results were as follows; 1. The ratio of male and female was 1.3:1, and youngest was 13 year-old and the oldest 86 year-old. 2. The peak incidence occurred from 5th to 7th decades, accounting for 78% of all cases (181/232), and there was a relatively high incidence of the disease in patients below 30 years of age at 7.8% (18/232). 3. Rectum and rectosigmoid region are the most frequently involved regions (127/23 2:54.8%). 4. The positivity of barium enema examination was 4.0% (232/5807), and its accuracy was 96.5% (224/232) . 5. The radiologic findings were classified into 4 groups, and they were annular encircling 62.9% (146/232), polypoid fungating 26.8% (62/232), infiltrating 8.6% (20/232), and primary ulcerating 1.7% (4/232) in order of frequency. 6. The linear length of the cancer ranged from 1.5 Cm to 15 Cm , and the average length was 5.5 Cm. 7. There was no statistical correlation between the length of lesion, the site, and the radiologic findings, and stages of the lesion (P:0.750-0.250). 8. The majority of colorectal cancers was adenocarcinoma (217/232:93.6%).

BACKGROUND: Adolescence offers unique opportunities for investment in health and well-being. The purpose of this study was to examine the common physical symptoms and diseases and medical utilization rate and the prevalence of health behaviors among school-aged adolescents. METHODS: This study was carried in 1998. Subjects consisted of 3,771 adolescents (ages 10 to 18) who attended an elementary, middle, and high school in Seoul and 3,246 parents. Self-report questionnaire was administered to the students and their parents to measure self-reported physical and psycho\social problems, practice of health behavior, medical care utilization rate, and the most common diagnosis. RESULTS: 1) Academic performance was the most common psycho\social problem for adolescents and their parents. 2) The perceived health status was highest in middle school students, lowest in female high school students. 3) As adolescents went to higher grades, the medical institute and dental clinic utilization rate tended to be decreased, and oriental clinic utilization rate did not change. The most common diagnosis during the past year was dental caries. The next most common diagnosis was respiratory infection. Accidents (males), headache (females) were more common in high school than middle school. 4) The most frequently reported symptom was fatigue in middle and high school students. More than half of female high school students reported fatigue, dizziness, headache, dysmenorrhea, hypersomnia during the last month. 5) The higher their grade was, the less adolescents practiced health behaviors. 21.9% of males and 1.9% of female high school students were smokers. 34.5% of males and 13.3% of female high school students drank alcohol on a regular basis. The prevalence of obesity was 12.0% in males, 10.0% in female high school students. Male adolescents tended to deal with stress with leisure activities, female adolescents did by talking about their problems with related people. CONCLUSION: This overview of health associated issues among adolescents provided a unique view of differences in health care needs between younger and older teens and between male and female teens. These data have meaningful implications for health promotion program for adolescents.

PURPOSE: We evaluated oncologic outcomes of chondrosarcomas and analyzed the disease-free survival rate of chondrosarcomas according to the various factors. MATERIALS AND METHODS: We performed a retrospective study for the disease-free survival rate of 48 chondrosarcomas, 44 of which underwent surgical treatment and followed up more than 18 months since 1993, and in the remaining 4 cases, the patients died before 18 months after surgery. The vsariables were location, tumor volume, histologic grade, stage, age at presentation and treatment performed. The mean follow up period was 43.8 months (1-196 months). RESULTS: The overall disease-free survival rate was 77.1% at mean 43.8 month follow up. The 5 year- and 10 year disease-free survival rates were 64% and 58% respectively. The histologic grade, stage, age at presentation revealed statistical significance on disease-free survival. All 9 patients treated with extended curettage for grade 1 central chondrosarcomas revealed disease-free survival with excellent functional outcome. CONCLUSION: The disease-free survival rate of chondrosarcomas mainly depended on histologic grade, stage and age at presentation. Local recurrence and distant metastasis also revealed statistically significant differences of disease-free survival rate. Comparing to wide resection, extended curettage for low-grade central chondrosarcomas in extremities were efficient methods with similar survival rate and less functional losses and complications.

PURPOSE: The purpose of this study was to evaluate the utility of two-phase dynamic CT, early and equilibrium pahse, in the preoperative staging of rectal cancers. MATERIALS AND METHODS: We performed incremental dynamic CT after rectal infusion of water in 34 patients with pathologically proved rectal cancers. Two-phase dynamic CT findings were prospectively analyzed and correlated with surgical and histopathologic findings. A total of 150ml of nonionic contrast medium was intravenously administered with a power injector at a flow rate of 5ml/sec for 30 sec, and two-phase images were obtained at 30 sec(early phase) and 2 min (equilibrium phase) after bolus injection. Local tumor staging and regional lymph node were classified by TNM staging. RESULTS: All 34 rectal cancers showed a moderate to marked enhancement in the early phase and a homogeneous and prolonged enhancement of the entire lesion in the equilibrium phase. T-staging of primary tumors were 85.3%(29/34) in early phase and 70.6%(24/34) in equilibrium phase. The accuracy in determining the perirectal fat invasion of rectal cancer was 92%(23/25) in early phase, and 72%(18/25) in equilibrium phase. The sensitivity & specificity of the regional lymph node metastasis were 63.6% and 79.1% in early phase, and 54.5% and 65.2% in equilibrium phase, respectively. CONCLUSION: Early phase dynamic CT was more accurate for the preoperative staging of rectal cancer than that at equilibrium phase.

Extradural hematomas are usually acute and rapidly progressing and the lucid intervals generally varies from a few moments to several hours. However, not uncommonly, an epidural hematoma may have a lucid interval lasting weeks, months or even years, which may present as a chronic epidural hematoma. Two cases have recently come under our care, demonstrating a paucity of objective neurologic abnormalities, but with extensive compressive extradural hemorrhage, which were found incidentally during the screening examination with the CT scanning.
